PUMP-CHAIN;

Specification of Letters'Patent. Patented Sept; 18, 1917.

Application filed November 4, 1916. I Serial No. 129,572.

isto provide a flexible chain forv elevating water from a well toa point above the surface of the ground at the same time causing air to, be circulated through "the water for purifying thesame and preventing. the water fromgbecoming stagnant.

As a further object of the inventionthe pump chain is provided withbuckets of two distinct types, certain .of the buckets of one type being connected together and having their ends connected to buckets ofthe other ty e. 1

it. further object of this invention is the provision of a pump chain which consists oi comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which de vices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and the accompanying drawings, wherein is illustrated the preferred form of my invention, in which;

Figure 1 is an elevation of a portion of the pump chain constructed in accordance with my invention.

Fig. 2 is a longitudinal section therethrough.

Referring to the drawing, wherein is illustrated the preferred form of my invention, and in which like numerals of reference indicate corresponding parts throughout the several views, it will be noted that two elements of the chain are disclosed in each figme of the illustration of the invention. It will be understood, of course, that the chain will consist of a plurality of link members forming a continuous chain for passing over a spoked wheel situated above the ground in the usual manner while the lower portion of the chain will be submerged in the water of the well. Thus, when the spoked wheel is rotated the links of the chain will be raised andlowered for raising the water from the well and for conveying air to the waterv in the well. I i, I

In the present invention, two types 101 links A and B are employed to constitute the The link A comprises a cylindrical cup 1 having a closedend Qand an open end 3. Integrally formed with the edge ofthe open end of the cylindrical cup is a plural{ 1ty of converging retaining arms ,4; welded or otherwise fastened .to a central rod 5']eX-' tended longitudinally through. the ,cup..,l.

The converging retaining arms-4 are extended inwardly at an angle from the edge of the cup andserve to'retain thecup in rigid positionand preventcollapsing of the same when the chain is in operation. Boththe meeting ends of the retaining arms land rod 5 is extended and bent to providev the con necting hook 6 which is adapted to be receivedin the loop of the adjacent link when ,the chain is entirely assembled. The lower end of the central rod 5 is provided with a circular eye 7 having a portion disposed beyond the closed end 2 of the cup. This con- 7 struction is obtained by providing the closed end. 2 with oppositely disposed openings j through which opposite sides of the loop 7 are extended after which the loop is soldered 7 or otherwise fastened to the closed end 2 for preventing leakage through the joint thus formed.

The type B of the links comprises a conabove described link. One end of the rod 8 is provided with a loop 9 for receiving the eye 7 of the link A and the opposite end of the rod has the eye 9, identical in construction with the eye 7 of the link A. In this instance, however, the lifting bucket comprises a circular disk 10 of rubber or other such similar material. Mounted upon the rod 8 and resting against the eye 9 is a spacing disk 11 adapted to fit into the concaved side 12 of the disk .10 and have one of its surfaces contacting therewith whereby the disk 10 will be held at the proper point upon the rod 8 so that the disk will not strike any of the teeth or spokes of the pump wheel (not shown). The opposite side of the disk 10 is convexed and. contacts witha nut 13 mounted upon the rod 8. An annular groove 14 is formed in the edge of thedisk thereby providing a double lip 15 neoting rod8 which is similar in construcfor contacting with the inner wall of the pump tubing (not shown).

It will be understood that these links may be made up into a. chain having a cup link A in each alternate position in the chain with the links B interposed therebetween. The links may be arranged in any preferred manner and .when assembled the bucket links B will cause the water to be quickly drawn through the tubing in the pump while the cups of the links A will also carry a certain amount of water to the top of the pump. The cups 1 of the links A, however, perform the additional function of carrying air into the water where it is permitted to circulate and rise to the sur face of the water in the well thereby purifying the same since it is well known that the oxygen contained in the air possess puritying qualities for water.

From the foregoing it will be observed that a very simple'and durable pump chain I has been provided, the details of which embody the preferred form. I desire it to be understood however, that slight changes in the minor details of construction" may be made without departing from the spirit of the invention or the scope of the claims hereunto appended.

I claim: 7 y l. A pump chain comprising a plurality of connecting rods having their ends linked together, cups mounte'c'l upon certain of the said connecting rods including hollow cylindrical member each provided with closed ends, the loop at the end of the said connecting rod being partially extended through the said closed end, and retaining arms at the open end of the cup. secured to the said connecting rod. 7

21A pump chain comprisinga plurality ofrods linked togetherat their ends, ce'rtain of said rods carrying cups each of which comprises a hollow cylindrical 'mem ber provided with a closed end having openings formed therein, the end of the corresponding connecting rod adjacent the closed end of each cup being provided with an'eye Copies ofthis patent may be olitained for five cent's eacligby' addressing the 'Gbmmissibn et'of' ratenm,
